The invention discloses a business flow
site selection optimization method based on multi-
source data fusion, and relates to the technical field of
big data processing and multi-
source data fusion, and the method comprises the following steps: obtaining multi-
source data of a to-be-detected region, constructing multi-source features, carrying out the cross-
modal fusion of the multi-source features through an adaptive
weight distribution mechanism, and generating a comprehensive feature representation; based on comprehensive feature representation, passenger flow trends and causal contributions of the candidate points in different scenes are output through a
causal inference method; taking the passenger flow trend and the causal contribution as input, establishing a multi-objective optimization model, performing solving, and outputting a comprehensive
score and a sorting result of the candidate points; constructing an explanatory index matrix according to the comprehensive
score and the sorting result in combination with a causal contribution result, and outputting
a site selection scheme through a visual platform; according to the method, the problems of single
data source and incomplete candidate point description in the prior art are solved by fusing the spatial geographic data, the space-time traffic data and the consumption behavior data.
